Though AK-225, also known as Asahiklin, has been a popular, and for the most part effective cleaning solvent for parts, metals, and materials for industrial companies that need to clean and degrease products, studies have proven that when the chemical agent is released into the air, it damages the Ozone Layer. These studies contradict a lot of the information that can be found online that sheds positive light on AK225. However, the fact remains that enough evidence points toward the negative effects of using AK225.

For industrial businesses that have come to rely on AK-225, the need to find a suitable replacement for a parts cleaning solvent that can clean and degrease the way AK225 could becomes a major priority. A solid AK225 alternative would be FluoSolv CX, which is a non-ozone depleting solvent alternative for AK225. The following is a list of reasons why industrial businesses that are still using AK225 can find solace in switching to FluoSolv CX.

  • The acceptable exposure limit for FluoSolv CX is more than double the figure of AK225
  • FluoSolv CX is a much faster drying solvent, which makes the chemical agent more ideal for vapor degreasing and cold cleaning applications for aerosol.Ecolink1
  • The makeup of both AK225 and FluoSolv CX are quite analogous, therefore, both cleaning agents have similar materials compatibility with all metals and nonmetals, including ceramics, and polymers.
  • AK225 is commonly used for the precision cleaning of composite assemblies in aerospace, complex geometry metal parts, as well as electronic and medical devices because of its high density and low viscosity. FluoSolv CX has similar thermal and physical properties that make it an excellent AK225 alternative and ideal choice for precision cleaning in the just mentioned industries.
  • Since no equipment modifications or change is required to the operations of industrial companies currently using AK-225, these companies can make a seamless transition to the environmentally safe and cost effective FluoSolv CX solvent.


AK225 Flushing Fluid Replacement: Two Options From Ecolink

AK225 flushing fluid (a.k.a. Asahiklin) enjoyed a long run as a go-to solvent for companies that perform routine degreasing and general cleaning of parts, surfaces, and materials. However, the solution’s ozone depleting properties rightly placed it on the Environmental Protection Agency’s (EPA’s) list of solvents that are banned or regulated. AK225 was primarily produced in Japan and has been banned from importation or production in the U.S. since the beginning of 2015.

AK225 Replacement Process: Two Options

As it would normally do, the EPA made AK225 flushing fluid users aware of the solvent’s impending ban before the ban was active. Some companies completed the phase out process in 2014, well before the date of the solution’s ban. The question is whether they implemented a seamless replacement for AK225 flushing fluid or have made do with a similar solution whose efficacy at removing soils doesn’t conform to the strength of the AK225 solvent it replaced.

If your company or organization is in this position, we recommend considering the following two options for finding a final, suitable replacement for AK225 flushing fluid: Implement Fluosolv CX solvent, which can be purchased directly from our online store, or have our team of experienced chemists create a custom solvent that perfectly conforms to your cleaning processes. Let’s take a look at each option.

  1. FluoSolv CX Solvent

Fluosolv CX has the same efficacy as AK225 and possesses several additional advantages, as well, including: an acceptable exposure limit that is nearly double the limit for AK225, no required equipment modifications (e.g. changes to parts washing systems) are necessary for using FluoSolv CX as an AK225 replacement, and FluoSolv CX dries faster than AK225, making the latter a better option for vapor degreasing and aerosol cold cleaning applications.

Moreover, FluoSolv CX is widely viewed as the number one replacement solvent for AK225.

  1. Customized Solvent

Most users should be able to implement FluoSolv CX as a drop-in solution for any ineffective AK225 replacement solution they currently use. However, there are inevitably outfits that need the formulation of FluoSolv CX tweaked to meet unique chemical cleaning requirements. In this situation, we recommend letting our team of chemists create the needed solution.

Once your custom solution is complete, we’ll even send you a free test sample, so you can be certain that the solution works as expected. From there, we can supply your custom solvent on a scheduled basis, or as the need for the cleaner arises. Choose the supply scenario best meets your requirements.

AK-225 Phase out: Find a Safe Alternative Now

replacing bad chemicalsFor those industrial businesses that are still using AK-225 to clean and degrease parts, metals, and materials, it may already be public knowledge that this cleaning and degreasing solvent, per federal regulatory demands, is being phased out, with the complete decommissioning of this solution set at the beginning of 2015. No matter how attached industrial businesses might have become to this effective, yet harmful cleaning and degreasing agent, it has been rendered hazardous by the powers that be and must be phased out. If your industrial business is facing the scenarios of having to replace the AK-225 cleaning and degreasing solution, then the time is now to find a safe alternative. Fortunately, Ecolink – a company that researches and designs green alternative, eco friendly cleaning and degreasing solutions – has found a safe alternative that industrial organizations can switch to right away and commence protecting its labor force and the environment.

The eco friendly, green alternative industrial solution that can replace AK-225, and even clean and degrease with more efficiency is called FluoSolv WS. FluoSolv WS is a non flammable and non toxic chemical cleaning and degreasing solution that has already become a replacement for older, hazardous cleaning and degreasing agents such as N-propyl Bromide, or nPB, and Trichloroethylene, also known as TCE. Now, FluoSolv WS is considered the best replacement solution for AK-225. This chemical solvent has a very high allowable exposure limit, making it a safe cleaning and degreasing agent for uses that include wipe and dip cleaners. FluoSolv WS provides outstanding solubility for fluorinated and hydrocarbon oils and grease. This solvent is compatible with almost any type of metals, glass, ceramics, and elastomers. Another important reason why FluoSolv WS is the chosen solution to replace AK-225 has to do with its zero ozone depleting potential – the opposite of what was wrong with using AK-225.

 AK225 Phase-out 12/31/14

Asahiklin3,3-dichloro-1,1,1,2,2-pentafluoropropane (HCFC-225ca) CAS #422-56-01, 3-dichloro-1,1,2,2,3-pentrfluoropropane (HCFC-225cb) CAS #507-55-1 are commonly applied as carrier fluids for silicone and fluorinated lubricants (electrical or sleeve testing, low temp drilling fluid, mechanical testing (low viscosity, high density) as a coolant;  heat transfer fluid; precision cleaning of small intricate metal and non-metal parts to remove minor oils, grease, finger prints and particulate matter; defluxing agent to remove solder flux after solder reflow step.

 Vapor Degreasing

Vapor DegreasingA primary application of AK-225 is in vapor degreasing systems including Baron Blakeslee, Branson Ultrasonics and Crest Ultrasonics.  Degrease any component (automotive, aerospace, medical instrumentation and implants, optics and electronic) from all light weight hydrocarbon oils such as engined fluids, brake fluids, hydraulic fluids as well as sub-micron particles. Deflux in applications where you cannot tolerate ionic or metallic impurities on the surface of parts post-cleaned. TechSpray® is a notable supplier. Call 888-996-8436 ext 125 to explore options.

Aerosol Applications

Aerosol ApplicationsAerosol applications of AK-225 require rapid evaporation, leaves no residue, powerful cleaning, non-flammable and plastic-safe. Avionic and electrical contact cleaning, all purpose degreasing and defluxing aerosols that meet this criteria cost $30 – $50 per can and be careful when reading propellant % to calculate “useable content.” When looking at alternatives you need to navigate need for solvency (heavy vs light), plastic safety, flammability and cost per can after measuring % propellant.
